Merge tag 'cxl-fixes-6.9-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull cxl fix from Dave Jiang:
"Add missing RCH support for endpoint access_coordinate calculation.
A late bug was reported by Robert Richter that the Restricted CXL Host
(RCH) support was missing in the CXL endpoint access_coordinate
calculation.
The missing support causes the topology iterator to stumble over a
NULL pointer and triggers a kernel OOPS on a platform with CXL 1.1
support.
The fix bypasses RCH topology as the access_coordinate calculation is
not necessary since RCH does not support hotplug and the memory region
exported should be covered by the HMAT table already.
A unit test is also added to cxl_test to check against future
regressions on the topology iterator"
